433 * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS)
434 into a single .so: liburcu-cds.so to have a single header/shared

467 * Remove leftover list_t type from urcu/list.h (namespace cleanup).
468 * urcu_defer: handle malloc error value.
469 * Update README file to describe urcu interaction with fork() when not
471 by an exec() system call.
473 2010-11-18 Userspace RCU 0.5.2
474 * Fix renaming error introduced in 0.5.0.
476 2010-11-18 Userspace RCU 0.5.1
477 * Fix renaming error introduced in 0.5.0. (incomplete fix)
479 2010-11-18 Userspace RCU 0.5.0
480 * Version 0.5.0 changes the API presented by memory model,
481 architecture abstraction and data structure primitives in
482 headers. The prefixes are, respectively:
483 - cmm_ : Concurrent Memory Model
484 - caa_ : Concurrent Architecture Abstraction
485 - cds_ : Concurrent Data Structures
487 2010-03-04 Userspace RCU 0.4.2
488 * Add generic uatomic ops support.
489 * Bugfix in urcu-bp. (rare garbage collection bug occurring in
490 multithreaded environment). Only affects urcu-bp users (UST).
492 2010-02-12 Userspace RCU 0.4.1
493 * s390: compilation fix.
495 2010-01-30 Userspace RCU 0.4.0
496 * API change: SIGURCU -> SIGRCU
497 * API changes: standardize on rcu_ prefix.
498 * API change: urcu_init -> rcu_init.
499 * urcu/config.h options renamed to CONFIG_RCU_HAVE_FENCE,
500 CONFIG_RCU_HAVE_FUTEX, CONFIG_RCU_SMP, CONFIG_RCU_COMPAT_ARCH.
501 ((moving from URCU -> RCU).
502 * library names changes: liburcu becomes the "default" version, using
503 sys_membarrier() when available, and using liburcu-mb as a
505 * The signal-based liburcu is renamed from liburcu to
506 liburcu-signal. People previously using the signal-based
507 "liburcu" will automatically be moved to the "default" liburcu
510 2009-11-16 Userspace RCU 0.3.1
511 * Add support for sparcv9 32-bit build.
512 * Update build system to use --host instead of --target.
514 2009-11-03 Userspace RCU 0.3.0
515 * API change for the "deferred work" interface.
517 2009-10-14 Userspace RCU 0.2.3
519 * Automated architecture detection, with i386 fallback.
520 * Detect if NR_futex is on the system, fallback on portable
522 * Add configure mode for UP-only systems.
524 2009-10-02 Userspace RCU 0.2.2
525 * Phases out rcu_publish_content() api.
526 * Adds type checking to urcu-pointer.h pointer exchange primitives.
528 2009-10-02 Userspace RCU 0.2.1
529 * small header dependency fix for rculist.h.
530 * new "liburcu-bp.so" : "Bulletproof RCU", made especially for
531 the UST userspace tracer. It's a library that sacrifices a bit
532 of read-side performance for automatically monitoring thread
533 creation/removal. See README for details.
535 2009-10-01 Userspace RCU 0.2
536 * Clarify usage of rcu_cmpxchg_pointer, rcu_xchg_pointer,
